Abstract
The pachytene and somatic chromosomes ofPhaseolus mungo L. (2n=22), were identified and classified on the basis of their relative length, arm ratio, chromomere pattern and nucleolar association. A comparison of the karyotypes during the somatic and pachytene stages, revealed that some chromosomes are of different relative lengths during the two phases. Thus, the two nucleolar organizer chromosomes are the 2nd and 3rd longest at somatic metaphase, but only 7th and 9th longest during pachytene. The pachytene chromosomes belong to the differentiated group.
